product specification doc: MB6022ASC-1L iii. reliability tests vibration test the microphone to have no interferance in operation after vibrations, 10hz to 55hz for 1minute full amplitude 1.52mm, for 2 hours at three axises. drop test the microphone unit must operate when dropped three times once on each axis from a height of 1m onto a metal plate. temperature test the microphone unit must operate within its sensitivity specifications after subjected to the following conditions: +85c for 240 hrs, and exposed to room temperature for 2 hrs. the microphone unit must operate within its sensitivity specifications after subjected to the following conditions: -40c for 240 hrs, and exposed to room temperature for 2 hrs. high low humidity test +60c at 95%rh for 240 hrs temperature cycle test after exposure at -40c for 45 minutes, at+20c for 10 minutes, at +85c for 45 minutes, at +20c for 10 minutes, 27 cycles. (the measurement to be done after 2 hrs of conditioning at +20c.) after any of the following tests perform ed, the sensitivity of the microphone unit shall not deviate more than 3db from its initial value. the microphone shall maintain its initial operation and appearanc e. measurements for tests with thermal requirements are to be done a fter 2hrs of condistioning at 20c. note: iv. dimensional drawing the information contained in this literature is based on our experience to date and is believed to be reliable and it is subjec t to change without notice. it is intended as a guide for use by persons having technical skill at their own discretion and risk . we do not guarantee favora ble results or assume any liability in connection with its use. dimensions contained herein are for reference purposes only. for specific dimensional r equirements consult factory. this publication is not to be taken as a license to ope rate under, or recommendation to infringe any existing patents . this supersedes and voids all previous literature. v. other issued date: 2006/11/1 version: a
